A Saudi royal didn’t quite get the red carpet treatment he expected in Hollywood. The prince descended on the Sunset Tower Hotel’s Tower bar Saturday with 10 bodyguards. Already seated at separate tables were Anjelica Huston, Bradley Cooper, John Mayer, Jason Reitman, and Jason Sudeikis with Vince Vaughn. Betsy Bloomingdale was dining with Barbara Davis. A diner tells us the royal’s people “insisted on four tables in one area for the guards to watch the prince.” But famed maître d’ Dmitri Dmitrov delicately said he couldn’t move others as, “The prince wasn’t the only royalty in the room.” He also told the guards they couldn’t stand behind the prince, as, “that looks tacky.” They wisely did as they were told.
